A container with an integrated drainage system. The container may include a pot used to boil pasta or other types of foods. The integrated drainage system may be configured with the pot to enable heated water to be drained from within the pot without having to pour the pasta and / or the heated water over the top rim of the pot (which typically releases dangerous amounts of steam). The drainage system may include a bell crank configured with a piston. The piston may include a lower sealing member that may correspond to an aperture in the bottom of the pot. Movement of the bell crank may cause the piston and its lower sealing member to open the aperture for drainage and / or to close the aperture for use of the pot.

The present invention discloses a semi-trailer-loaded turbine fracturing equipment, which adopts a linear connection of the whole equipment and a special chassis design, so that the center of gravity is double lowered to guarantee its stability and safety, the structure is simpler, the investment and operation costs are decreased, the risk of total breakdown of the fracturing site is reduced, and the equipment has a good transmission performance and is suitable for continuous operation conditions with long time and heavy load. The plunger pump is improved in that the distance between the center of rotation of the bellcrank and the center of rotation of the crankshaft is optimized so that the rated input power is increased to 5000-7000 hp, the transmission ratio of the reduction gearbox integrated on the plunger pump is optimized so that the maximum input speed can reach 16000 rpm, the superhigh speed allows the reduction gearbox to be connected directly to the turbine engine to address the problem that the turbine fracturing equipment is decelerated through two reduction gearboxes, thus decreasing the weight of the vehicle and reducing the overall size of the equipment.

A landing gear assembly for an aircraft with a forward brace to attach to an airframe of the aircraft; an aft brace to attach to the airframe and coupled the forward brace; a piston pivotally coupled to forward brace; a bellcrank linkage having a first end, a second end, and a pivot point therebetween such that a first portion of the linkage extends from the first end to the pivot point, and a second portion of the linkage extends from the pivot point to the second end, and the pivot point is pivotally coupled to the aft brace and to the piston; a primary strut pivotally coupled to forward brace and the aft brace; and a secondary strut pivotally coupled to linkage and a pivot point proximate the primary strut. The assembly has a deployed configuration when the piston is retracted, and a retracted configuration when the piston is extended.

This invention provides a well-drilling mechanism and a well-drilling transplanter with the mechanism installed. The mechanism includes a frame, a power drive unit, a first sprocket, a first crank, a first crank connecting rod, a second crank connecting rod, a second crank, a second sprocket, and a hole-forming device. The power output shaft of the power drive unit is connected to the first sprocket. The rotation center of the first sprocket is connected to one end of the first crank, and the other end of the first crank is hinged to one end of the first crank connecting rod. The rotation center of the second sprocket is hinged to one end of the second crank, and the other end of the second crank is hinged to one end of the second crank connecting rod. The other end of the second crank connecting rod is connected to the hole-forming device, and the other end of the first crank connecting rod is hinged to the middle of the second crank connecting rod. The first sprocket and the second sprocket are connected by a chain. This invention effectively solves the problems of high labor intensity, discontinuous drilling, severe soil backflow, unsatisfactory work efficiency, difficulty in soil penetration, and easy damage to the drill bit in the prior art.

A latch positioning mechanism for an aircraft door includes one or more locking members configured to be partially driven into a frame around the door via rotation of a pivot pin. A frame bumper extends outside of the door in a pre-catch position for contacting the frame. A catch bellcrank is operatively coupled to the frame bumper, and a biasing member biases rotation of the catch bellcrank to bias the frame bumper into the pre-catch position. The catch bellcrank is configured to contact a catch cam when the catch bellcrank is biased into the pre-catch position such that the catch cam prevents release of the one or more locking members for locking the door. Upon the frame bumper contacting the frame when the door is closed, the catch cam is released enabling the one or more locking members to be moved into a locked position.

A corner head includes a driving body, a driven body, a bell crank, and a support pin. The driving body and the driven body both include a guiding portion. The bell crank includes first and second guided portions and is rotatable about the support pin. The guided portions are slidable within the respective guiding portions of the driving body and the driven body. When the driving body is moved in a first direction, the first guided portion is guided by the guiding portion of the driving body and moves in a second direction perpendicular to the first direction; the bell crank rotates about the support pin; the second guided portion is guided by the guiding portion of the driven body and moves in a third direction different from the second direction; and the driven body moves in a fourth direction perpendicular to the third direction.

High lift systems for aircraft and associated methods are provided. A high lift system includes a movable high lift device, an inboard track for guiding an inboard portion of the high lift device, and an outboard track for guiding an outboard portion of the high lift device. An actuator drives the high lift device between a retracted position and a deployed position. The actuator is disposed inboard of the inboard track. An inboard bell crank connects the actuator to the inboard portion of the high lift device. An outboard bell crank connects the actuator to the outboard portion of the high lift device. A connecting link connects the inboard bell crank to the outboard bell crank such that the outboard bell crank driveably connects the actuator to the outboard portion of the high lift device via the connecting link and the inboard bell crank.

Regarding the door handle, a relatively simple structure is used to enable sequential electric and mechanical unlocking as the door handle stroke increases. [Solution] The door handle is equipped with a mechanism that transitions between four states, a signal generation unit that generates an electrical signal based on the movement from the second to the third state, and a door latch drive unit that performs electric unlocking in response to the electrical signal. The first bell crank rotates from the first to the second rotation position in response to the transition from the second to the third state, and rotates from the second to the third rotation position in response to the transition from the third to the fourth state. The second bell crank rotates from the fourth to the fifth rotation position in response to the transition from the third to the fourth state. The lever is connected to the first bell crank so that the second bell crank rotates from the fourth to the fifth rotation position in conjunction with the rotation of the first bell crank from the second to the third rotation position, and the rotation of the second bell crank from the fourth to the fifth rotation position realizes mechanical unlocking. Door handle device It will be disclosed.
